초록

본 논문에서는 CPW에 식각된 T자형 DGS를 제안하고 전송이론을 이용하여 전파 방사를 포함한 손실률, BW(3-dB fractional bandwidth) 등을 closed-form 형태의 수식으로 유도하고 이의 영향에 대해 분석한다. 제안된 T자형 DGS 구조는 기존의 아령형 DGS 구조보다 약 5.5배정도 큰 커패시턴스(C) 조절 특성을 가진다. 또 DGS 등가회로의 R, L, C값과 손실률, BW, 저지대역 공진 각주파수($\omega_0$)의 상관관계를 정량적으로 이끌어낸다.

Abstract

In this paper, we propose a T-shaped DGS for CPW and provide the closed-form solutions for power loss rate, and bandwidth of the DGS. The proposed T-shaped DGS structure has a range of capacitance(C) 5.5 times wider than the dumbbell-shaped DGS structure. In addition we also analyze relations between R, L, C values of the DGS equivalent circuit and total loss rate, BW, $\omega_0$ of the DGS.
